Several European leaders have come to Greenland's defense over President Trump's threats to acquire the autonomous Danish territory.

In a statement issued Tuesday, the leaders wrote, "Arctic security remains a key priority for Europe and it is critical for international and transatlantic security.

"NATO has made clear that the Arctic region is a priority and European Allies are stepping up. We and many other Allies have increased our presence, activities and investments, to keep the Arctic safe and to deter adversaries. The Kingdom of Denmark – including Greenland – is part of NATO," they also wrote.

"Security in the Arctic must therefore be achieved collectively, in conjunction with NATO allies including the United States by upholding the principles of the UN Charter, including sovereignty, territorial integrity and inviolability of borders. These are universal principles, and we will not stop defending them.

"The United States is an essential partner in this endeavor, as a NATO ally and through the defence agreement between the Kingdom of Denmark and the United States of 1951. Greenland belongs to its people. It is for Denmark and Greenland, and them only, to decide on matters concerning Denmark and Greenland."

Danish Prime Minister Mette Frederiksen, French President Emmanuel Macron, German Chancellor Friedrich Merz, Spanish Prime Minister Pedro Sánchez, U.K. Prime Minister Keir Starmer, Italian Prime Minister Giorgia Meloni, and Polish Prime Minister Donald Tusk signed the statement.

The leaders of the Netherlands, Greece, Luxembourg, and Slovenia also backed the statement, POLITICO reported.

Belgian Prime Minister Bart De Wever posted on X on Tuesday, "I support my Danish colleague Mette Frederiksen’s call for respect for sovereignty among NATO allies. The West is strongest when it stands united and works together, not when it divides itself."

The statements came after Trump said on Sunday, "We need Greenland from a national security situation."

Greenland’s government on Tuesday requested an urgent meeting with Secretary of State Marco Rubio to discuss the U.S.'s "significant statements" about the territory.

Earlier on Tuesday, Frederiksen met Canadian Prime Minister Mark Carney to discuss security in the Arctic, saying she appreciated “Canada’s strong support to the Kingdom of Denmark in the current situation.”
